ABSTRACT:
A keyboard (10) is disclosed including a flexible display membrane (36) overlying a plurality of pressure-responsive switches (28). The display membrane (36) can be electrically addressed to display location indicia (48) indicating the position of an underlying switch (46), and functional indicia (50) indication the function of the key (46). Informational text (58) can also be displayed on the flexible display (36) indicating the choice of switches to effect a desired function. An interactive exchange of information between the keyboard user and a processing system (14) can be achieved to accomplish a desired function. Graphical information can be input to the processing system (14) by an array (90) of pressure-responsive elements (91). Graphics input by the array (90) can be reproduced on an overlying portion (96) of the flexible display membrane (36).
